Numerical investigation of flow structure and bifurcation phenomena of confined plane twin-jet flows

Abstract

This work numerically investigates laminar plane twin-jet flows with side-wall confinement. Time-dependent computations on the full physical domain are performed in light of the possible emergence of flow unsteadiness and an asymmetric pattern. Of particular concern is how wall-confinement and jet momentum influence the transition of flow patterns. Results presented herein provide further insight into the complexities involving issues such as the variety of flow structure and the related bifurcations, jet–jet and jet–wall interactions, and flow instability involved in the confined twin-jet flow field.
